12809 * c-common.c (c_common_nodes_and_builtins): Since variants of

12822 (build_type_attribute_qual_variant): When building an attribute
12823 variant, its canonical type is the non-attribute variant. However,
12824 if the attributes are target-dependent and they differ, we need to
12825 use structural equality checks for this type.
12826 (build_qualified_type): A qualified type is not equivalent to its
12827 unqualified variant; set the canonical type appropriately.
12828 (build_distinct_type_copy): When building a distinct type from
12829 another type, the new type is its own canonical type.
12830 (build_variant_type_copy): When building a new type variant, we
12831 assume that it is equivalent to the original type.
12832 (build_pointer_type_for_mode): When building a pointer type, also
12833 build a canonical type pointer.
12834 (build_reference_type_for_mode): When building a reference type,
12835 also build a canonical type reference.
12836 (build_index_type): When we can't hash an index type (e.g.,
12837 because its maximum value is negative), the index type requires
12838 structural equality tests.
12839 (build_array_type): Build the canonical form of an array type.
12840 (build_function_type): Function types require structural equality,
12841 because they contain default arguments, attributes, etc.
12842 (build_method_type_directly): Ditto for method types.
